From: Bill Spitzak <spit...@gmail.com> This makes the speed of the demo more accurate, as the filter generation is a visible fraction of the time it takes to do a transform. This also prevents the output of unused filters in the gnuplot option in the next patch.
Note this is not dependent on other patches, as use can choose linear and bilinear in the existing version.
